1, Grain Rain is the sixth solar term among the 24 solar terms and the last solar term in spring. Every year from April 19 to April 2 1 day, when the sun reaches 30 degrees of the yellow meridian, it is Grain Rain, which comes from the old saying "Rain gives birth to a hundred valleys". At the same time, it is also the best time for sowing, transplanting and ordering beans.

2. "Qingming Snow Rest, Grain Rain Frost Rest". According to meteorologists, Grain Rain is the last solar term in spring, and the arrival of Grain Rain solar term means that the cold wave weather is basically over, and the temperature rises rapidly, which is extremely beneficial to the growth of cereal crops.

3. As the saying goes, "Rain over a hundred valleys". With sufficient and timely rainfall, cereal crops can thrive. Grain Rain solar terms have such a meaning. Grain Rain season, Sichuan Basin, "young flowers fall, cuckoos cry at night, peonies bloom, and cherries are ripe. The natural scenery tells people that it is late spring. At this time, the temperature in the basin rose rapidly. Generally, the average temperature in late April has reached 20℃ to 22℃, which is more than 2℃ higher than that in mid-April, except for the northern and western parts of the basin. In the eastern part of the basin, there is often a high temperature of more than 30 degrees for a day or two, which makes people feel very hot. The low-altitude valley area in southwest Sichuan is used for entering summer.

4. The climatic characteristics of high temperature in spring in the basin are beneficial to the early cultivation measures of crops in Da Chun. The suitable planting temperature of Polygonum cuspidatum is 65438 08℃ to 22℃, which can be satisfied at this time. Experience in the old arid area of the river basin proves that planting Osmunda japonica early after Grain Rain can seal vine leaves before summer drought, enhance drought resistance and obtain high and stable yield. At this time, there is abundant rainfall in the eastern Sichuan Basin, with rainfall of about 30 to 50 mm in late April of the year. The first rainstorm usually occurs in this period, which is beneficial to rice planting and the growth of corn and cotton at seedling stage. However, the rainfall in most other areas of the basin is less than 30 mm, so irrigation measures should be taken to alleviate the impact of drought. The mountainous area of the western Sichuan Plateau is still in the dry season, and the precipitation is generally only 5 to 20 mm. The rainfall around Grain Rain in the basin often "sneaked into the night with the wind, and moistened things silently", because "late rain" appeared most frequently in April and May. "It often rains at night and the river sill is clear", which is very suitable for crop growth and harvest.
